The Cocondensation Reaction of Difluorosilene with Diborane: New Polyfluoropolysilanes.
Abstract
The cocondensation reaction of S1F2 with B2H6 at a -196C surface gives a product which, by low-temperature evaporation in vacuo, yields nonvolatiles and diborane derivatives of the 1,1-fluorosilylated type, possibly of the heterocyclic class 1,1-(Sif2)(n)B2H4. These decompose very easily at low temperatures (possibly autocatalytically) to form nonvolatiles and polyfluoropolysilanes; such products also come from the original cocondensation reaction. They include the known compounds SiF4, HSiF3, (SiF3)2O, Si2F6, HSi2F5, and Si3F8, and the new compounds H3SiSiF3, H2Si(SiF3)2, probably HSi(SiF3)3 and Si(SiF3)4 (neither very stable), a somewhat unstable H(SiF2)2SiF3, and other volatiles which are more difficult to identify.
